Calculate the osmotic pressure in pascals exerted by a solution prepared by dissolving 1.0 g of polymer of molar mass 185,000 in 450 mL of water at 37°C.

Given,


Volume of water, V = 450 mL = 0.45 L


Temperature, T (37 + 273)K = 310 K


1.0 g of polymer of molar mass 185,000


Number of moles of polymer, n = 1 / 185,000 mol


We know that,


Osmotic pressure, π =


=


= 30.98 Pa


= 31 Pa (approx)
